Genome Biology

Genomics is a discipline in genetics concerned with the study of the genomes of organisms. The field includes efforts to determine the entire DNA sequence of organisms and fine-scale genetic mapping. The field also includes studies of intragenomic phenomena such as heterosis, epistasis, pleiotropy and other interactions between loci and alleles within the genome. In contrast, the investigation of the roles and functions of single genes is a primary focus of molecular biology or genetics and is a common topic of modern medical and biological research. Research of single genes does not fall into the definition of genomics unless the aim of this genetic, pathway, and functional information analysis is to elucidate its effect on, place in, and response to the entire genome s networks. For the United States Environmental Protection Agency, "the term "genomics" encompasses a broader scope of scientific inquiry associated technologies than when genomics was initially considered. A genome is the sum total of all an individual organism s genes. Thus, genomics is the study of all the genes of a cell, or tissue, at the DNA (genotype), mRNA (transcriptome), or protein (proteome) levels." The

Specific fatty acids may worsen Crohn's disease

Some research has suggested that omega-3 fatty acids, abundant in fish oils, can relieve inflammation in Crohn's disease. But a new study using software developed by Duke scientists hints that we should be paying closer attention ...

Early warning gene signature for Alzheimer's

A 'gene signature' that could be used to predict the onset of diseases, such as Alzheimer's, years in advance has been developed in research published in the open access journal Genome Biology.

Your gut development during infancy can have lifelong implications

The suckling period (infancy) in mice is critical for epigenetic changes (changes that affect the way genes are expressed) in the development of stem cells in the intestine, potentially affecting intestinal health for life. ...

Redefining colorectal cancer subtypes

There is a long-standing belief that colorectal cancer (CRC), which causes some 50,000 deaths in the United States each year, can be categorized into distinct molecular subtypes. In a paper published recently in the journal Genome ...

How do neural cells respond to ischemia?

A group of researchers from the Lomonosov Moscow State University, in collaboration with their Irish colleagues from the University College Cork, has studied the early response of cells to ischemia, which is a restriction ...

Identical twins can share more than identical genes

An international group of researchers has discovered a new phenomenon that occurs in identical twins: independent of their identical genes, they share an additional level of molecular similarity that influences their biological ...
